no wait I got it. When he attacks you with that condition it works as a retrogade but he can still damage you by using that ability on you again and again and again. Anyway if you're psychological you can use dark infusion to attack yourself, wich will heal you and let your teammates kill him, and use infusion on them if they get hurt (clemens only attacked me). After a while he will stop using comdition and you can just kill him the old fashioned way and turn of relentless on veradux (you should put it on so he doesn't heal-damage you)
